Blunt Traumatic Retropharyngeal Hematoma with Respiratory Symptoms: A Systematic Review of Reported Cases

Background. In patients with blunt trauma, particularly geriatric patients and those with minor trauma, an insidious retropharyngeal hematoma (RH) may deteriorate and have lethal consequences. We review the relevant literature to elucidate the clinical characteristics, treatment, complications, and outcomes of blunt traumatic RH with respiratory symptoms. Data Resources. We reviewed 57 case reports and added one case from our hospital for data analysis. A total of 68 cases were included in this review. Results. The ages of patients ranged from 13 to 94 years, and geriatric patients (age >66 years) constituted 61.2% of the reviewed patients. Falls (54.4%) and traffic accidents (35.3%) were the major trauma mechanisms. Most patients’ symptoms developed within 24 hours of blunt trauma (95.2%), and 73.5% of patients with RH had at least one associated injury. Many patients underwent conservative treatment for RH (63.2%). Surgical treatment (23.5%) and transarterial embolization (8.8%) were used to control retropharyngeal hemorrhage. Twelve patients died; RH and cervical spinal injury were the direct causes of death in 5 patients, whereas the other 7 patients died because of cardiac, pulmonary, or gastrointestinal causes or withdrawal of life support. Conclusions. Geriatric patients constituted the largest proportion of patients with RH, and minor trauma was adequate to result in RH in elderly people. The cornerstone of RH management is airway management. Surgery and transarterial embolization are commonly used to control active bleeding in patients with RH. The long-term outcome depends on patients’ associated injuries and in-hospital complications.

Delayed onset postoperative retropharyngeal hematoma after anterior cervical surgery with a sequela of tracheal stricture: a case report

Background Among the several complications associated with anterior cervical discectomy and fusion (ACDF), airway compromise is considered one of the serious life-threatening conditions and usually requires emergent treatment, including airway establishment and hematoma evacuation surgery. Postoperative retropharyngeal hematoma commonly occurred during the on immediate phase with airway compromise, but have a rarity on late onset of this complication. Enlightened by this existing fact, we report the first case of delayed onset postoperative retropharyngeal hematoma after anterior cervical surgery with a sequela of tracheal stricture. Case presentation A 55-year-old male underwent ACDF for disc herniation at C5–6 that had not responded to conservative treatment over 3 months. The symptoms significantly improved after surgery, and he was discharged on postoperative day 3. On the 7 days after ACDF, the patient complained of sudden-onset left-deviated neck swelling. The follow-up plain radiographs and neck-enhanced computed tomography (CT) scans showed anterior and right lateral displacement of the airway including the trachea by a large retropharyngeal hematoma. We performed an emergent forceful endotracheal intubation that was maintained for 2 days until the patient underwent hematoma evacuation surgery. On the second day after hematoma evacuation surgery, the patient complained of hoarseness with a foul breath odor. Laryngoscopy showed tracheal ischemic mucosal damage that had been induced by forceful endotracheal intubation. Antibiotics and systemic corticosteroids were administered, and the symptoms improved. One month after hematoma evacuation surgery, he complained of dyspnea on exertion, and laryngoscopy showed tracheal stricture. The patient underwent bronchoscopic dilatation and is doing well without recurrence of symptoms. Conclusions Early surgery to remove the delayed onset retropharyngeal hematoma, rather than forceful endotracheal intubation followed by delayed surgery, might yield better results and avoid unexpected complications of tracheal stricture.

The Spontaneous Retropharyngeal Space Hematoma: How to Manage?

Introduction: Spontaneous Retropharyngeal Hematoma (SRH) is a rare affection which occurs without traumatism. Case report: A 68 years old woman brought to the emergency department with a cervico-thoracic swelling rapidly increasing in size without any previous traumatic history or anticoagulant medication. Complicated by dysphagia and dysphonia without signs of dyspnea. The clinical examination revealed a painful anterior cervico-thoracic swelling with an ecchymotic cupboard on it. Cervico-thoracic CT scan found a voluminous retro-pharyngeal collection, spontaneously hyperdense, extended to the oropharynx and antero-superior mediastinum without further lesions. Biological assessment was without abnormalities. The diagnosis of retropharyngeal hematoma was retained. The treatment was based on corticosteroids and antibiotics drugs with strict clinical and radiological monitoring. With conservative treatment, the evolution was favorable, marked by progressive regression of the hematoma until its disappearance and an absence of recurrence after a retreat of one year. Conclusion: The clinical presentation of a retropharyngeal hematoma out of an evocative context is misleading and lead to radiological investigation without delaying the treatment which varies from supervision to surgery according to respiratory status and evolution under strict control.

Rare but Foreseeable: Rapidly Expanding Retropharyngeal Hematoma After Fall from Height

Case Presentation: An elderly man presented to the emergency department after a fall from a 15-foot height. Initial examination revealed signs of head and neck trauma without airway compromise. Computed tomography imaging identified cervical fractures at the first and second level with a retropharyngeal hematoma. In discussion with the trauma service, the patient was admitted to the hospital for airway monitoring. After 10 hours he clinically deteriorated, resulting in acute respiratory failure, and ultimately required intubation. The patient was intubated with a hyperangulated video laryngoscopy, and a surgical set-up was also prepared. The intubation was uncomplicated and resulted in clinical improvement. The patient was extubated after three days without difficulty and was ultimately discharged following an uncomplicated hospital course. Discussion: Retropharyngeal hematoma is a rare but significant clinical condition. Rapid decline and airway compromise have been described. Patients often require intubation and mechanical ventilation to avoid airway obstruction and respiratory failure. Coagulopathies should be reversed, if present. Prompt recognition and treatment of this condition is crucial to successful management.
